cuckoo

Chap on a TV program got to the £500 level and only had phone a friend left. The quiz master asked if he was sure he wanted to go for the £1m jackpot, and he decided to.

So the question was " What bird does not make a nest?"
" OOH that is a tough one, I will phone a friend". So he rang Paddy in Ireland and after a lot of thought Paddy said it was a cuckoo. Are you sure? definately a cuckoo says paddy
So the guy gave cuckoo as the answer and won the £1m jackpot

So please he had won he went over to Ireland to share his winnings with Paddy

He asked why Paddy was sure it was a cuckoo

Easy said paddy, everyone knows cuckoos live in clocks
